Abstract

A neurostimulator device for use with groups (e.g., more than four groups) of electrodes. The neurostimulator may include a stimulation assembly configured to deliver different stimulation to each of the groups. The neurostimulator may also include at least one processor configured to direct the stimulation assembly to deliver stimulation to the groups. The stimulation delivered to at least one of the groups may include one or more waveform shapes other than a square or rectangular wave shape. The processor may receive data from one or more sensors and use that data to modify the stimulation delivered. The neurostimulator may be configured to communicate with an external computing device. The neurostimulator may send data to and/or receive data and/or instructions from the computing device. The computing device may use information collected by one or more sensors to at least partially determine stimulation parameters to communicate to the neurostimulator.

Claims28

Dependent claims

1-51. (canceled)

A device for use with a plurality of electrodes, and one or more sensors, the device comprising:

a stimulation assembly connectable to the plurality of electrodes, the stimulation assembly being configured to deliver stimulation to selected ones of the plurality of electrodes when the stimulation assembly is connected to the plurality of electrodes;
a sensor interface connectable to the one or more sensors, the sensor interface being configured to receive signals from the one or more sensors when the sensor interface is connected to the one or more sensors;
at least one processor connected to both the stimulation assembly and the sensor interface, the at least one processor being configured to direct the stimulation assembly to deliver at least one complex stimulation pattern to the selected ones of the plurality of electrodes, and to receive the signals from the sensor interface, the at least one processor being further configured to modify the at least one complex stimulation pattern delivered by the stimulation assembly based on the signals received from the sensor interface.

Dependencies are inferred from the claim text.
